The Barnstable Fire District will hold a special meeting on March 5 and Cotuit Fire District on March 6, both seeking authority to implement changes in its health insurance coverage for district employees.

Under consideration is the adoption of a change in state law that limits the collective bargaining aspects for the selection of health plans. Communities and districts that adopt the law expect to see savings in the cost and sharing of premiums.

The Hyannis Fire District and the Centerville-Osterville-Marstons Mills Fire District have already adopted similar language. The Barnstable Town Council was to hold a workshop on the subject this week, with a vote to authorize possible.

The Barnstable Fire District will also take up some by-law changes, one seeking to change the annual meeting date from the first to second Monday of May.

The March 5 special meeting in Barnstable begins at 7:30 p.m. at the fire station in the village center.

The Cotuit Fire District special meeting begins at 6 p.m. at the fire department, 64 High Street, Cotuit.
